Gooooogle—some conceptions


I’m impressed with the products as Google coming up with the most innovative web applications on the WWW. In recent times, the most amazing application from Google is ORKUT. Impressed with its vivid features, I was surprised to read some of its facts. Orkut, a social network service run by Google is founded by its co-worker Orkut Büyükkökten. The guy,a Turkish software Engineer is currently doing his PhD. from Stanford University,created the website to find his lost girlfriend. He used it to link his friends believing one day he could find his Girl friend. Naturally when anyone becomes extravert, rumors starts spreading ….many saying that Google is paying him for every scrap we write to others, others write to us and so on…and the most absurd fact that he will be the richest man in the world by 2009. Hardly to believe rite??

I’ve heard of the working environment in Google that employees can utilize 20% of their time on personal interests. But that should be beneficial to Google’s business. No par I can say Google has the greatest minds in the world. I was astounded to hear that inorder to get into Google a person must clear 14 level of selection process. It is all about intellectuality and noesis. In my life time during my job hunt, I’ve crossed a max of 4 levels. I can say if Einstein had been alive he would have worked in Google with the greatest minds on earth and had come out with more ground-breaking technologies on the internet.
My kudos to Google from this blog!!

Coke+Mentos-A gushing info


There has been a lot of discussion online about why Diet Coke and Mentos make such an interesting combination. What everyone can agree on is that the carbon dioxide that has been compressed into the soda escapes so rapidly that the pressure pushes the soda out of the bottle. It’s like shaking a bottle before you open it, but even more dramatic.
 
Gum Arabic? Not So Fast.
 
Several people theorized that a substance called gum arabic in the Mentos breaks the surface tension of the soda, allowing the carbon dioxide bubbles to escape rapidly. This explanation doesn’t completely work. One thing that casts doubt on the gum arabic theory is that several items (like pennies!) that contain no gum arabic whatsoever also cause soda to foam violently. Several chemists have since stepped forward to say that while gum arabic may contribute to the reaction, that can’t be the only cause.
Making Lots of Bubbles
 
These chemists are saying that the primary cause is physical, not chemical. Their explanation: nucleation sites. If you have a liquid that is supersaturated with gas (like soda, which is pumped full of carbon dioxide), a nucleation site is a place where the gas is able to form bubbles. Nucleation sites can be scratches on a surface or specks of dust – anywhere that you have a high surface area in a very small volume. That’s where bubbles can form.Mentos seem to be loaded with nucleation sites. In other words, there are so many microscopic nooks and crannies on the surface of a Mento that an incredible number of bubbles will form when you drop it in a bottle of soda. Since the Mentos are also heavy enough to sink, they react with the soda all the way to the bottom. The escaping bubbles quickly turn into a raging foam, and the pressure builds dramatically. Before you know it, you’ve got a big geyser happening!

 
The BIG question!
 
So is it dangerous to drink soda and eat Mentos? Well, a lot of the fizz goes away as you drink. Then when bubbles are released in your stomach, your stomach can expand a bit, and it also has ways of releasing excess pressure. Do not, repeat, do not be stupid and test the limits of your stomach. Don’t even think about it.
